Spiders are small (with the exception of the Acromantula) eight-legged and eight-eyed creatures. They are very common and come in many species, varying from region to region; all are carnivorous and some are venomous, but for the most part they are relatively harmless and can sometimes be used as a potion ingredient. The largest species of spider is the Acromantula, which also has the ability to speak. Spiders are known for spinning webs. The webs of the Acromantula are large and dome-shaped. Spiders of all sizes fear the Basilisk above all other things, which caused those at Hogwarts to flee into the Forbidden Forest in the 1992–1993 school year.
